Abstract
PURPOSE: To obtain the substrate for magnetic disk without causing oxidation coating crack, by polishing alumite plate obtained by carrying out anodic oxidation after heat-treating at a specific temperature preliminarily.
CONSTITUTION: Heat resisting property of coating is improved and crack initiation is prevented, by polishing after heat-treating at 150W350°C preliminarily, at the time of carrying out anodic oxidation of Al plate surface and offering produced oxidation coating for magnetic recording medium. Accordingly, alumite substrate for magnetic disk having a high flatness, is able to obtain easily.
